Altura de mudas obtidas por enraizamento de estacas, em função de diferentes doses de osmocote e raspagem nas estacas
(Embrapa Café, 2016) Daia, D. T. A.; Rezende, T. T.; Carvalho, S. P.; Silva, J. A.; Oliveira, L. L.; Andrade, M. L.; Almeida, D. L.
Objetivou-se neste trabalho verificar a altura das mudas obtidas por enraizamento de estacas, em função de diferentes doses de adubo (Osmocote) e raspagem nas estacas.
Características comerciais de mudas de café produzidas com diferentes fontes de fósforo e bactérias promotoras de crescimento de plantas
(Instituto Internacional de Ecologia, 2023-03-30) Ferraro, A. C.; França, A. C.; Machado, C. M. M.; Aguiar, F. R.; Oliveira, L. L.; Braga Neto, A. M.; Oliveira, R. G.
Considered the economic engine of many countries, the coffee culture represents an important component of the agricultural chain in Brazil. The growing values of commercialization, planting areas, and crop productivity require the acquisition of quality seedlings, which must receive adequate nutritional support through efficient fertilizers. Slow and controlled-release fertilizers, such as organominerals, gain prominence when it comes to increasing efficiency in the use of phosphorus, as well as plant growth-promoting bacteria (PGPB) with phosphate solubilizing characteristics. This study aimed to evaluate the effect of different sources of mineral and organomineral fertilizers, inoculated and non-inoculated with PGPB on the quality parameters of coffee seedlings. In general, the P sources used in the experiment positively interfered with the development of coffee seedlings. This proves that there is a need for nutritional supplementation for the good development of the seedlings. Among the sources used, the organomineral in granulated form showed better performance in coffee seedlings' growth and physiological parameters, proving to be a viable alternative to commonly used fertilizers. The addition of PGPB showed a significant advantage for seedling quality variables.
